Background

GOAL - Establish safety of same day robot assisted bariatric surgery (RMBS) in general, especially the more complex DS & CS based on our 2012-2023 experience.

Methods

1226 consecutive patients (pts) underwent RMBS from Jan 2012 through Nov 2023 by CWLS at SFH SDS center using standard techniques. Pts who met CWLS same day surgery (SDS) d/c criteria: pain control w/o IV meds, po >300mL, ambulate, Hct & Lytes wnl, w/o complication on CT Abd & Pelvis with PO & IV contrast & adequate support were d/ced within ~2-6h (SDS n=623). Their 30d MBSAIP outcomes were compared with those that stayed overnight(s) (ES n=603). We chose the 2d outcome to test the safety of our SDS d/c criteria.

Results

There was no mortality. The two groups were comparable wrt weight, BMI, ASA & comorbidities such as diabetes, hyperlipidemia, GERD & OR duration. There were no significant differences between the groups with respect to the 2d or 30d outcomes (Table 1):There was no significant difference in 2d & 30d 0utcomes between DS, CS, SADI c/w VSG within SDS (Table 2):There was a strong tendency towards SDS from 55/86 (64%) in 2020 to 63/65 (97%) in 2023.

Conclusions

2d and 30d outcomes after RMBS SDS is not different from ES. The majority of DS & CS pts can be d/ced on the day of surgery. Close follow-up cannot be overemphasized.
